    Collapse overview

    Dr. Sadasivam is an Associate Professor in the Division of Health Informatics, Population and Quantitative Health Sciences, University of Massachusetts Medical School (UMMS).  His PhD training was in computer engineering, in the area of software and systems engineering. His PhD dissertation was focused on designing a meta-composite framework to support the personalized composition of tools to support human interaction needs.  In collaboration with health care researchers, he has lead the development of multiple providers- and patient-facing eHealth and mHealth technologies. 

    At UMMS, his research goal has been to create new knowledge involving a new generation of persuasive technology designed to help patients and clinicians better work together toward improving health and well-being.  This research goal has led to two lines of federally-funded research:

    1. Innovations in computer-tailored health communication (CTHC) systems
    2. Innovations in peer recruitment on social media:

    He is currently leading two NCI funded R01s (R01 CA190866-05 and 1R01TW010647-03), a Patient-Centered Outcomes Research Institute funded award (CDR-1603-34645),  and 1 National Science Foundation proposal (1722708) as collaborative PI (similar to multi-PI). He has completed a five year  NCI-funded K07 award to train in Cancer prevention and control with a focus on smoking cessation (K07 CA172677-05), as well as an NCI funded R21 (1 R21 CA158968).
